Beyond wanting to limit a bounce back, why else would someone put up 2-3-4k ask walls right after a sharp decline, right on the edge. They were way too big, way too consolidated to be bots. There were still enough bids walls if you actually wanted to sell you could have. Not to mention the ask walls came up right after the final coin dump to 105-110. You can explain away lots of coins being sold. I find it hard to explain away people aggressively pushing the ask wall preventing any serious bounce back.
